MINNEAPOLIS (AP) -- Xcel Energy Inc. and other plaintiffs are suing General Electric Co., claiming it hid a known defect in a turbine that broke down at one of its plants and led to millions of dollars in losses.
The turbine outage happened at the Sherco 3 electric generator in Becker in 2011. The turbine was being tested after an outage when it began to vibrate and broke apart, starting a fire.
Xcel says the 22 months of repairs that followed cost it more than $200 million. Its lawsuit alleges that GE and its affiliates knew about a defect in its turbine blades for decades and had documented earlier failures and improved its design, but never told Xcel about the problem.
